USING THE OUTRIGGERS AND THE BOOM
Lower the outriggers to the supporting position and check the position with the levelling
indicator. Maximum permitted erection inaccuracy is +1°.
Check that all wheels are off the ground.
If the Access Platform is unevenly supported and no ground sensor is active, the boom
does not rise from the transport support, and an alarm sounds when the pedal is pressed.
If you suspect the strength of the soil, extend the boom completely in a horizontal angle,
and extend and retract the boom at each outrigger. If the soil yields, rearrange outrigging.
Use additional support boards when required.
When the platform is listed, if the soil under an outrigger yields or the Access Platform has
been erected inaccurately, the outrigging may become loose. In this situation an alarm
sounds when the pedal is being pressed. Loose outrigging does not prevent the use of the
boom. Retract and lower the boom immediately onto the transport support, and rearrange
the outrigging. Use additional support soil boards when required.
The boom can be driven with several simultaneous movements for fast and flexible
operations.
For lifting movement, the boom control valve has a special valve stem design for smooth
start and stop of the boom. The turning device is also equipped with a similar special valve
stem. If you are going to work in the same place for a long time, switch off the engine
using the key in the platform, and restart the engine to move to the next location.
When lifting the boom off the transport support and lowering it back onto the transport
support, pay attention to the location of the drive valve stem.
Danger of collision!
